Statistics are a wonderful thing IF you understand them. Last year was a record low for sea ice extent in the Arctic, which means the following year should move back toward the mean. The long term trend of ice volume and sea ice is clear and the use of a short term view is nothing more than misleading cherry picking.

One of the central issues is believed to be why the IPCC failed to account for the “pause” in global warming, which they admit that they did not predict in their computer models. Since 1997, world average temperatures have not shown any statistically significant increase.

The summary also shows that scientist have now discovered that between 950 and 1250 AD, before the Industrial Revolution, parts of the world were as warm for decades at a time as they are now.

Despite a 2012 draft stating that the world is at it’s warmest for 1,300 years, the latest document states: “'Surface temperature reconstructions show multi-decadal intervals during the Medieval Climate Anomaly (950-1250) that were in some regions as warm as in the late 20th Century.”

So what? In the age of the dinosaurs it was even warmer. It happens that the rate of temperature rise recently has been unprecedented and after analyzing the influence of natural forcings experts have concluded most of the warming is due to AGW.

Already we have had a taste of the nonsense to come: a pre-announcement to the effect that “climate scientists” are now “95 per cent certain” that humans are to blame for climate change; an evidence-free declaration by the economist who wrote the discredited Stern Report that the computer models cited by the IPCC “substantially underestimate” the scale of the problem; a statement by the panel’s chairman, Dr Rajendra Pachauri, that “the scientific evidence of… climate change has strengthened year after year”.

As an exercise in bravura spin, these claims are up there with Churchill’s attempts to reinvent the British Expeditionary Force’s humiliating retreat from Dunkirk as a victory. In truth, though, the new report offers scant consolation to those many alarmists whose careers depend on talking up the threat. It says not that they are winning the war to persuade the world of the case for catastrophic anthropogenic climate change – but that the battle is all but lost.

A crappy blog is all you have? Really not much to convince the fence sitters is it?

When less energy is reflected more energy comes in and the decrease in reflected energy of 2.25W/m2 is more than adequate to account for the 0.4°C of observed global warming between 1980 and 2010 without invoking any effect from CO2; leaving the IPCC “attribution by default” with no validity.

“The Stefan-Boltzmann equation gives intensity of radiation, W/m2, emitted by a body at temperature T. It is analogous to fluid pressure, kg/m2. Stefan and Boltzmann called it intensity, not heat transfer, because it is intensity, not heat transfer. (It becomes heat transfer in maximum case emitting to 0K surroundings, so it is a max heat transfer. Real transfer is always less.) All bodies radiate with an intensity and they all experience a pressure. But for a fluid to flow there must be a driving force, a pressure difference. Physics teaches the fluid flows from high pressure to lower at a rate proportional to the pressure difference. The pressure at the bottom of the sea is high but uniform so no fluid flow.

For radiant energy to flow, transfer from one body to be absorbed by another body, heating it, there must be a driving force and that force for radiant energy transfer is an intensity difference. Physics teaches that the radiant heat flows from high intensity, to lower intensity, at a rate proportional to the difference (TH4 - TL4). Two identical glowing radiators facing each other radiate intensely but without any heat transfer between them.

The GHGT error is assigning to that second intensity term in the radiant heat transfer law an energy flow from cold to hot. Just because there is an algebraic term in the equation for cooler body radiating intensity does not mean it corresponds to a rate of heat transfer from cold to hot.

Atmospheric CO2 radiates with same intensity in all directions but the direction and rate of heat transfer to surroundings depends on surrounding’s radiating intensity. Energy transfer is asymmetric. So if the K-T 333 back-radiation arrow signifies direction of downward radiation intensity in all directions, ok, if they point it in all directions. But K-T labeled their diagram energy flows, and their back-radiation arrow 333 cannot be a flow, absorbed by surface, warming it further. Hence we have the dispute about semantics of physics which GHE believers dismiss with derision. “

Plus the religious warmers claim only 0.39 percent (a trace gas) of our atmosphere does all of this. Not possible.

So there is no green house effect and the Earth is at the blackbody temperature which has been incorrectly calculated? No, so the attempt to use the semantics of a general explanation as a flaw in science is the sophistry beign discussed.
